Working principle of TPSC157M004R0070

Tantalum capacitors use a solid tantalum pentoxide film as their dielectric material. A solid tantalum pentoxide film is formed on the surface of a tantalum metal foil electrode. When a voltage is applied, a small number of charge carriers are injected into the dielectric and migrate toward the opposite electrode. The accumulation of charges at the interface between the dielectric and the electrodes creates an electric field with across the dielectric. This electric field produces an electrostatic capacitor that stores electric energy.

A tantalum capacitor contains two electrodes and a dielectric material between them. The dielectric material is usually composed of a tantalum pentoxide film, which is highly resistant to leakage. The two electrodes are usually made of a tantalum metal bar, with a positive and negative electrode at opposing sides. When a voltage is applied to the capacitor, electric charge accumulates between the two electrodes, forming a reversible electrostatic field. This allows the capacitor to hold a charge.

The TPSC157M004R0070 offers an ESR (equivalent series resistance) of 0.1 ohms, which is much lower than what is offered by other types of capacitors. This low ESR helps to reduce voltage ripple and provide better filtering capabilities. Additionally, it has an excellent temperature coefficient and can operate at high frequencies without any problems.

Overall, the TPSC157M004R0070 is an effective and reliable capacitor, ideal for a variety of applications. It can provide excellent filtering, reduce voltage ripple, and provide high-speed operation. Its low ESR, high temperature coefficient, and small size make it a popular choice for a wide range of applications, including power supplies, consumer electronics, and automotive systems.
